Application filed March 16, 1914. Serial No. 824,895.

To all whom it may concern? Be it known that 1, DAVID O. Rors'rnn, a citizen of the United States, residing at St.

Louis, Missouri, have invented a certain new" and useful Improvement in Methods of and Apparatus for synchronously Making Motion-Pii-tures and Sound-Records, of which the following is a full, clear, and exact description, such as will enable others skilled f in the art to which it appertains to make and use the same, reference being had to the'accompanying drawings, in which Figure 1 is a vertical section taken lengthwise through the center of an apparatus of my improved construction; Fig. 2 is a plan view of the apparatus with a part thereof in horizontal section.

My invention relates to a new and improved method of and apparatus for synchronously making motion pictures and sound records,'the principal object of my invention being to provide a. comparatively simple and inexpensive apparatus which can be readily utilized for taking motion pictures and making sound records which when reproduced will be absolutely synchronous.

In taking motion pictures the object to be photographed is necessarily located a certain distance away from the camera and the methods heretofore practised for making I records of the sounds produced by photographed objects have not always resulted in perfect synchronisms between the reproduced pictures and sounds, and in my im-,

proved method and apparatus, Ipropose to provide means wherein all the sounds made by an object which is being photographed will be drawn through a tapered chamber to a point of concentration, from .whence they are delivered directly to the sound recording device, which latter is located adjacent to and operated synchronously with the motion picture camera.

With the above and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed.

Referring by numerals to the accompanying drawings, 10- designates a housing which is adapted to be'occupied by the object to'be photographed-and the interior of this housmg is lighted in any suitable manner, preferably by means of a series of arc lamps 11, located in theupper portion of the housing and also by means of mercury vapor lamps v12 located adjacent to the side walls of the housing.

Formed in the rear wall of the housing is a series of openings which are partially in-' closed by small housings 13 and located in these small housings are small electric fans 14:.

Connected to the front wall of the housing and projecting outwardly therefrom is one end of an elongated hollow cylinder 15 which tapers gradually toward its outer end, said cylinder being constructed of any desired material, but preferably of glass. in the small outer end of this tapered cylinder is a receiver 16 and leading therefrom is a tube 17 which connects with the recorder 18 of a sound recording device 19. Located immediately adjacent to this sound recording device and adapted to be operated synchronously therewith is a motion picture camera 20, the same having a tubular exten- Located sion 21 which extends into the tapered cylinder 15' so that the lenses of said camera are focused upon the center of the housing 10. Leading from the small outer end of the cylinder 15 to a suitable suction producing device such as a fan is a tube 22.

In the operation of my improved apparatus, the camera 20 and sound recording device 19 are simultaneously operated and the object to be photographed occupies the housing 10. The fans 14' and suction producing device connected to tube 22- are simultaneously operated, thereby creating a flow of air through the housing 10, and through the tapered cylinder 15, which air finally passes through pipe 22 and discharges from the suction device connected thereto. The motions of the object within the housing 10 are photographically reproduced upon the film in the camera 20 and the sound waves produced by said object are carried through the cylinder 15, with the draft of air through; out, which sound waves are concentrated at the small outer end of the cylinder 15 where they are caught by the receiver 16 and transmitted to the reproducer 18 through tube 17 The recorder 18 acts directly upon the wax cylinder or disk of the sound recordin device, and thus the sounds made by the o ect within the housing 10 are synchronously recorded with the pictures made by the camera 20.

By producing a current of air through the housing and cylinder practically all the sounds made by the object within said housing are carriedpdirectly to the transmitter 16 and as the c 1inder'15 is tapered toon an object within a housing and transmitting,- the sounds made by the object within thehousing by means of a current of air ward its outer en cordingdevice l9. I i

An apparatus of my improved construction is comparativel simple, can be easily operated and rprovi es means whereby mo tion pictures and sound records of absolute synchronism c'anbe readilyand cheaply proin shown and described, withoutdepartingQ from the spirit ofm'y invention, the scope of which is set forth in the appended claims.

I claim: e

1. The hereindescribed method of syn chronously making motion pictures and sound records, consisting in synchronously operating a motion picture camera and .a sound recording device, focusing the camera which iS gra-dualIy' condensed during its travel from the housing to the. reproducer of the sound recording device.
